CDC Front-end • Items • Maintain TRG output firmware • Manpower • YTL (KEK) • Problems • Noise hit reduction • Cross-talk reduction • Radiation damage of AVAGO modules • Do we need spares for AVAGO modules? • Should we monitor light yield of the front-end AVAGO module? • Monitoring tools • Hit rates • Noise hits? • Cross-talks? • CDC front-end upgrade • Only one wire layer (priority layer) of drift time are sent • If we send drift time of more layers, better tracking (fitting) would be possible • Close contact with CDC FE development groups 5 yoshihito.iwasaki@kek.jp
